specification of Letters Patent. Patented Mar. 13, 191'?.

Application led October 20v 1915. Serial No. 56,938.

To all whom t may concern:

Be it knownthat I, RICHARD C. SELLERS, a citizen of the United States,residing in Swarthmore, Delaware county, State l of Pennsylvania, haveinvented a Calendar, of which the following is a speciiication.

One object of my invention is to provide a relatively simple andconvenient form of perpetual calendar 4particularly adapted for thoughby no means confined to, use on a desk ;-the arrangement of parts beingsuch that in addition to a holder there shall be provided a series ofmonth cards and a second series 'of year cards designed for use 'withsaid month cards to display the .dates vof the days of any month in anyparticular year.

I further desire to provide a calendar which in addition to the abovefeatures shall have its two series of cards so constructed and marked asto properly display the names and figures Anecessary to indicate thedays of the week, the months and the years. These objects and otheradvantageous ends I secure as hereinafter set forth, rer"- erence beinghad to the accompanying drawings, in which,

Figures 1 and 2 yare respectively4 a front elevation and a verticalsection of a calendar constructed according tomy invention; Figs. 3 to 9inclusive are elevations of the v year cards' formingV part of mycalendar;

and o Figs. 10 to 23' inclusive are elevations of the month cardsdesigned to be used in connection with the holding frame and the yearcards. y

In the above drawings 1 represents a rectangular or other suitablyformed frame which may be of any suitable construction having a cavityfor the reception and positioning of month and year cards and includinga conveniently removable' backv2 whereby access may behad to thecards'for the purpose of changing their relativepositions. In the caseshown the frame with its back is held in ay position slightly inclinedfrom the vertical by means of a supporting member 3, and the card cavityis substantiallyrectangular in outline so that the year as well as themonth cards will more or less closely t within it.

As shown in Figs. 10 to 23 the month cards have siX horizontal rows offigures, each containing from one to thirteen figures, 'with theexception of the top and bottom rows which never. contain more thanseven.

from it'by seven. The first row' of ligures always begins by the numeral1 as does also the second row except in case it extends to the eXtremeallowable leftvhand limit,.when it; begins with the numeral 2. It shouldbe noted that there is provideda card foreach month in theyear and twoeXtra cards, one 4:tor January and oneV for February `(Figs. 22 and 28)for use in place. of f the normal month cards (Figs. 10 and 11)' duringany leap year. All of these month cards'fit into and are held inposition by the frame l 'and that particular month card which it isdesired to display is overlaid by a suitable one of the year cards,which is of the same general dimensions and likewise fits the frame 1.so as to be immovably heldthereby. Each of the month cards hasVprojecting from its upper edge a tab or ear l on which is displayed thename of the month to whichits particular arrangement of numerals 'isysuited and' `in the case shown these tabs extend from the vmiddle ofthe top of each card.

The year cards on the other hand have tabs 5 projecting from the ends oftheir upper edges anddisplay numerals indicating the year for which theyare primarily adapted, althoughas shown, eachA of said cards has alsodisplayed'upon it numerals indicating certain other years for which it1s likewise adapted. Moreover each of these i year cards has formed init a rectangular opening whose length is equal to the lengthl occupiedon =one of the month cards. for seven consecutive numerals of one of itsrows and the lheight of the opening 7 is equal to the combined verticalwidth of siX oi said rows.

v Eachof the seven year cards devised by me has itsV opening in one ofseven possible positions,each of which is displayed to the right or leftof the one nearest it by a distance equal to the horizontal width of oneof the numeral spaces of the month cards. For example, the year cardshown in Fig. 4 has its opening 7 displaced to the right of the positionoccupied by the opening in the year card shown in Fig. 3, a distanceequal tothe width of one vertical column of figures ont-he monthk cards,and similarly the Vwhich the particular set of numerals eX- posed, givesthe correct dates to the various days, it being noted that each yearcard immediately over its particular opening 7 is provided with aline ofseven initials or other day-designating symbols inline with f the sevenvertical columns of figures visible through said opening and belongingto the set of figures on a month card mounted under it, in order toindicate the days of the week. Y.

For example, as shown in Fig. 6, the year card i'or 1909 if placed inthe frame 1 over any one of the month cards shown in Figs. 10 to 21inclusive, will permit certain nu merals on said card tobe displayedthrough its opening such as will indicate the proper dates of the daysof the week for that particular month and year. The same card will alsogive correct readings for an indefinite number of other years of whichtwo in the particular case indicated are 1915 and 1920. Since 1920 is aleap year it, as well as any other year card bearing numerals indicatingleap years, must in order to give correct dates, be used with specialleap year month cards for the months of January and February,illustrated in Figs-22 and 23, in place of those shown in Figs. 10 and11.`

When the package of month cards with theV one which it is desired todisplay uppermost, is placed in the frame 1 immediately back of' theproper year card, the tab f1 bearing th(l name of the month is displayedbetween the two tabs 5 of the card bearing the primary numerals for theyear, so that said numerals and month numerals are displayed in the sameline as shown in Fig. 1. It will of course be understood that the frontopening in the frame is of suificient width to permit the figures of anymonth card to be visible through the opening 7 of any year cardregardless of the particular one of said cards used and the height ofsaid frame opening is atleast sufhcient to permit the display of thenumerals on the year and month cards respectively. The frame l is sodesigned as to accommodate all of the eXtra year cards as well as all ofthe month cards not in useV at any time, although said-extra cards maybe otherwise accommodated without departing from my invention.

I claim 1. The combination in a calendar of aseries of month cards eachhaving rows of consecutive figures representing the dates of the days ofthe month, certain of said rows including more than seven figures; witha year card designed to fit over any one of said month cards and havingan opening placed to display only those figures of one month cardrequired to indicate the dates of the days of the month designated onsaid card in the year designated on said year card.
